The can opener mechanism includes a transport wheeland the cork puller mechanism includes a pressure generating device.Both the transport wheel of the can opener mechanism and the pressuregenerating device of the cork puller mechanism can be actuated by asingle lever which is pivotably mounted to the graspable body orhousing.

BACKGROUND OF THE INVENTION The present invention broadly relates to amultipurpose utensil and, in its more specific aspect, deals with acombination device which serves to open bottle, cans, containers, casksof all types, and similar type articles.

Different type utensils or devices are utilized for opening packages orreceptacles of the most varying type in the household and commercialenterprises such as hotels, restaurants, inns, rooming houses, and soforth. Accordingly, can openers have become known to the art by means ofwhich tin or sheet metal cans can be opened. On the other hand, in orderto open bottles, cork pullers have been used, or for the opening ofbottles with metal closures, special hook-shaped keys or other types ofimplements have been employed. Moreover, different devices are used ifit is desired to punch a pouring opening in the can or container or thelike.

The use of such different type utensils or devices has associatedtherewith different drawbacks. On the one hand, in order to store thesevarious utensils a relatively large amount of place is required and, onthe other hand, it is easy to misplace such devices so that at the exactmoment that it is necessary to use them they are not always immediatelyavailable.

SUMMARY OF THE INVENTION Accordingly, it is a primary object of thepresent invention to provide an improved multipurpose utensil orcombination device of the type described which effectively overcomes theaforementioned drawbacks.

Another, more specific object of the present invention, relates to animproved combination device for opening bottles, cans, casks, containersand the like in a relatively simple and reliable manner, wherein thesame device can be used for the opening of these sundry typereceptacles, and where the changeover in the use of such device for onepurpose to another is very simple and can be carried out quickly andeasily by the user.

Still a further noteworthy object of the present invention is to providea multipurpose utensil or combination device of the aforementioned typewhich combines into a single unit mechanism for opening various types ofcontainers or receptacles, such as bottles, cans, casks,

3,570,027 Patented Mar. 16, 1971 and the like, all with a minimum ofeffort and ease, and wherein the use of the device presents no greatdifiiculty since simple manipulations permit the user to selectivelybring into play a desired type of opening mechanism provided at thecombination device.

A further significant object of the present invention relates to amultipurpose utensil for opening different types of bottles,receptacles, containers as specified herein, wherein the multipurposeutensil itself is relatively inexpensive to manufacture, quite efficientin the performance of its intended use, can be easily operated by theuser, is not readily subject to breakdown, and provides in a single unitmultifarious tools for carrying out various desired opening operationsas such bottles, containers, receptacles, and the like.

Now, in order to implement these and still further objects of theinvention, which will become more readily apparent as the descriptionproceeds, the invention contemplates the provision of a multipurposeutensil or socalled combination device which incorporates a housing orbody member which can be readily gripped by the user. A can openermechanism as well as a cork puller mechanism are accommodated at thehousing. The can opener mechanism has a transport or drive wheel and thecork puller mechanism has a pressure generating device for popping thecork. Both the transport wheel of the can opener mechanism and thepressure generating device of the cork puller are actuated by a singlelever which is pivotably mounted at the graspable housing.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be betterundertsood and objects other than those set forth above, will becomeapparent when consideration is given to the following detaileddescription thereof. Such description makes reference to the annexeddrawings wherein:

:FIG. 1 is a schematic side view of a preferred embodiment of theinventive multipurpose utensil or combination device incorporating thegraspable housing and the actuation lever which is secured at suchhousing, and wherein the cork popping needle unit is detached, in otherwords not shown mounted in its operable position;

FIG. 2 is a side view of the combination device depicted in F161 1, butthis time viewed from the opposite side thereof, and showing thethreadably mounted cork puller needle unit and the actuation leverlocated in its operable position;

FIG. 3 is a longitudinal sectional view of the combination device ormultipurpose utensil shown in FIG. 2 but without the threadably mountedcork puller needle unit being shown; and

FIG. 4 is a side view, partly in cross section, of the combinationdevice depicted in FIG. 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT Describing now the drawings, inFIG. 1 reference numeral 1 designates the graspable housing or bodymember which can be conveniently held in the hand of the user. As willbe more fully explained hereinafter, a cork puller mechanism, a canopener mechanism as well as further utensils, all of which will beconsidered shortly, are conveniently accommodated at the graspablehousing 1. As best evident by referring to FIG. 4, at the one narrowside In of the graspable housing 1 there is provided a slot 1b out ofwhich there can extend the actuation lever mechanism 2. The latteradvantageously incorporates a safety catch or slide 3 by means of whichthe actuation lever 2 can be fixed at the graspable housing or bodymember 1. As will 'be observed by referring to FIG. 1, when theactuation lever mechanism 2 is fixed in this manner it bears fiushly atthe housing 1 and closes the opening or slot 112 provided at the narrowside of such housing.

As already alluded to above, the inventive multipurpose utensil orcombination device embodies a cork puller or cork popping mechanismwhich, in the exemplary embodiment, incorporates a needle valve unit 4which can be threaded, as will be explained more fully hereinafter, ontothe upper end face of the graspable housing 1, as best shown byreferring to FIG. 2. This needle valve unit 4 possesses threading 5 atthe side thereof which is opposite the side which is threaded into thehousing 1. This threaded portion or threading 5 can be used, as will bedescribed more fully hereinafter, for screwing the needle valve unit 4,if desired, into the cork which is to be removed. Furthermore, the corkpopping needle 6 is mounted at the needle valve unit 4. As also evidentby inspecting FIG. 2, a selector switch or lever 7 is located at theregion of the lower end face of the housing 1. This selector switch orlevel 7 has been shown in an operational position wherein thecombination device can be used as a can opener for instance, whereas ifthe selector switch 7 is moved into the operational position towards theright of FIG. 2 the device has then been manipulated so that it isprepared to serve as a cork puller.

Considering initially the can opener mechanism it will be seen that suchincorporates a transport or drive wheel 8 and a cutting wheel 9. A pairof roller members which are disposed to each side of the cutting wheel 9cooperate with the transport or driving wheel 8 and this cutting wheel9. These roller members 10 are advantageously provided with a springarrangement which will be considered more fully shortly.

The components of the multipurpose utensil or combination device whichare located internally of the graspable housing 1 are best seen byreferring to FIG. 3. Thus, for instance, it will be apparent that arecess 11 has been provided within the graspable housing 1. A conicalportion 12 merges with the recess 11 and, a channel 13, in turn, mergeswith the lower end of the conical portion 12. The hollow compartmentconstituted by the recess 11, the conical portion 12 and the channel 13serves to house the needle valve unit 4 together with the needle 6during non-use of the cork puller.

Furthermore, internally of the housing 1 there is located a cylinder 14which is closed at its upper end by an insert member 15. A piston 16travels within the compartment of the cylinder 14, the lower region ofthis piston 16 being extended downwardly to provide a piston rod 17. Thepiston member 16 and the piston rod 17 are provided with alongitudinally extending bore 17a serving to receive a portion of thespring member 18. The other portion, namely the upper portion of thespring member 1 8, is guided by a cylindrical projection 19 provided atthe insert member 15. In the position of the spring member 18 shown inFIG. 3 it possesses a certain bias or prestress and urges the lever 2into its operational position. In order to secure the operating lever 2at the graspable housing 1 the safety catch or slide 3 is displaced intoengagement with the bore 20 provided at the upper end face of thehousing 1.

The insert member 15 possesses a threaded recess portion 21 at its upperface or end, into which the needle valve unit 4 can be threadablyattached. The needle valve unit 4 operably communicates with the innercompartment of the cylinder 14 through the provision of the channels 22and 23. A suction valve 24 is arranged at the piston rod 17, whereas theconventional pressure valve is provided at the needle valve unit 4 andis not visible in the drawings.

A link member 25 is pivotably mounted to the piston rod 17 by a boltmember 26 or equivalent fastener. The opposite end of this link 25 isconnected with the actuation lever 2 by means of another bolt 27 or thelike. This actuation lever 2 is mounted by means of a bolt member 28 ina bracket member 29- This bracket member 29 possesses a substantiallyU-shaped configuration, wherein the base portion 30 forms a downwardlyextending closure portion and both of the bracket-like leg members 31thereof extend upwardly. Both of these bracket-like leg members 31 ofthe bracket 29 form two walls in which there are mounted the bolt orshaft member 28 and the transport wheel 8 of the can opener mechanism.The actuation lever 2 is rotatably mounted by means of this bolt orshaft member 28. Additionally, the bracket legs 31 are provided withslot means 32. A bolt member 33 piercingly extends through both of theslot means 32, this bolt member 33 being fixedly mounted in the wallportions of the graspable housing 1. Furthermore, the bolt member 31piercingly extends through a recess or cutaway portion 34 provided atthe actuation lever 2, this recess 34 possossing an approximatelytriangular configuration, as shown.

Turning attention further to the construction of the actuation lever 2it will be recognized that such incorporates a toothed segment 35 at theend which is located in the graspable housing 1. This toothed segment orgear segment 35 meshes with a pinion or gear 36. Pinion 36 is mountedupon the shaft member 37 of the transport or driving wheel 8.Furthermore, this pinion 36 has an internal bore possessing a number ofnotches or teeth 38 with which engage a pawl 40 subjected to the actionof a spring 39. The notches or teeth 38 provide a ratchet structure forthe pawl 40. Due to this construction it is possible for the pinion 36to only entrain the transport wheel shaft 37 and therefore the transportwheel 8 in one direction corresponding to the direction required for theproper functioning of the can opener mechanism.

At the region of the lower end face of the graspable housing 1 there isarranged a slide mechanism 41. This slide mechanism 41 travels in twogrooves or ways 42 provided at the side walls of the graspablehousing 1. Furthermore, slide mechanism 41 is provided with a structuralsteel member 43, which is flexed or bent at one side to form a tool 44for opening bottles having a metal closure as well as bottle caps whichcan be cut and then lifted away. At the opposite ends of the structuralsteel member 43 there is provided a portion which possesses asubstantially triagular tip 45, this tip 45 being downwardly bent, asshown in FIG. 3. Thus, when the slide mechanism 41 is displaced to theleft of FIG. 3, it is possible to use this tip portion 45 to press apouring opening out of the bottom of a can or other type of cask orcontainer. A screw 46 which is mounted at the slide mechanism 41 extendsinto a slot 47 so that the lateral displaceability of the slidemechanism 41 is conveniently limited. A spring member 48 generates acertain friction to thereby fixedly retain in this manner the slidemechanism 41 at the momentarily assumed operational position.

By referring to FIG. 4 it will be apparent that the cutting wheel 9 ofthe can opener mechanism is surrounded by a collar 49 which is inclinedwith respect to the walls of the graspably housing 1. The clampingrollers 10 which are arranged to each side of the cutting wheel 9 arerotatably mounted at the roller support member 50. This roller supportmember 50 is conveniently formed of sheet metal which bears from theoutside against the wall of the housing 1 and, furthermore, by means oftwo substantially hook-shaped flexed fingers or flaps 51 engages with arespective recessed portion 52. Spring members 53 are arranged in therecessed portions 52, these spring members serving as pressure springswhich urge the roller support member 50 against a stop means 54.

The heretofore described multipurpose utensil or combination devicefunctions in the following manner:

(1) Operation of device as cork puller Initially, the security catch 3is retracted out of engagement with the bore 20 so that the operating oractuation lever arrives at the position shown in FIG. 3 under the actionof the spring member 18. At the same time the selector switch or lever 7is placed into the position corresponding to the working position forthe cork puller mechanism. Consequently, the substantially U-shapedbracket 29 is displaced into the lower position depicted in FIG. 3,which is defined by the elongated slot 32 and the bolt member 33. Nowthe needle valve mechanism 4 together with the cork popping needle 6 isremoved from the hollow compartment defined by the components 11, 12 and13 and is threaded via its threaded portion 4a into the cooperatingthreaded recessed portion 21 of the upper end face of the insert member15. The cork puller or cork popping device is now ready for operation.The needle 6 is then pushed through the cork of a bottle or the like,whereafter one hand is used to carry out pumping motions by means of theoperating or actuation lever 2. Thus, due to pressing of the actuationlever 2 against the graspable housing 1 the piston member 166 will bedisplaced until it reaches the lower end of the insert member 15. In sodoing, the air is conveyed through the channels 22 and 23 via thepressure valve located in the needle valve unit 4 through the hollowneedle 6 into the air compartment of the bottle to be opened. Thepumping motion previously described is continued for such time untilsufficient pressure is available to pop out the cork.

Furthermore, it should be appreciated that during operation of themultipurpose utensil for popping a cork a particularly large stroke isproduced which is composed of two components, namely, in the oneinstance, the stroke which results due to the rotation or pivoting ofthe lever member 2 about the bolt member 28 and, on the other hand, dueto the lifting of the bracket member 29 until the bolt 33 is located inthe lower position of the elongated slot 32. This partial stroke isprovided in that during the movement of the actuation lever 2 thecutaway or recess portion 34 moves along the contour of the bolt 33.

In the event that the cork cannot be removed in this manner, which couldoccur if the cork has not been sufiiciently rigidly fixed into thebottle, then the threading located at the needle valve mechanism 4 canbe threaded into the cork. As a result, a sufficient sealing action isachieved so that also a satisfactory pressure can be generated forpopping out the cork. However, the threading 5 of the needle valve unit4 which has been threaded into the cork can also be advantageously usedas a corkscrew in order to completely remove a cork which has not beenentirely pulled out of the bottle.

The graspable housing 1, the operating or actuation lever 2, the insertmember 15, the needle valve body unit 4, the piston 166 with its pistonrod 17, and the link 25, are all advantageously formed of a plasticpossessing sufficient hardness. This renders possible, for instance, inthe case of the piston member 16 that its sealing collar 16a can beformed of one piece together with the piston member 16.

(2) Operation of the device as a can opener In this instance theselector switch or lever 7 is brought into the appropriate positionwhich corresponds to the working position of the can opener mechanism.Now, if the actuating lever 2 is actuated then the bracket member 29 israised and remains in this upper position during use of the device as acan opener. During this time the bolt member 33 will be located at thelower end of the elongated slot 32. In this position the transport ordriving wheel 8, as best shown in FIG. 4, engages beneath the cuttingwheel 9. At the same time the roller members bear upon the indicated canedge portion and thus, under the spring action of the spring members 53,press the can against the transport wheel 8 so that it will bepositively entrained, This transport or driving Wheel 8 possesses anumber of notches 660 at its periph- 6 ery, which are not symmetrical,rather are inclined towards one direction so that they intensely fixedlyhook themselves in one direction at the can.

The resilient roller members 10 impart to the can opener mechanismespecially advantageous characteristics, so that also cans withpronounced variations in direction or contour can likewise be openedwithout difficulty. Furthermore, in order to be able to open very smallcans an opening 55 can be provided at the transport wheel 8 into whichthere can be inserted a suitable key or the like so that the cover ofsuch cans can be rolled up. The rotation of this key likewise occursthrough the movements with the actuation lever 2.

Also, the can opener mechanism of this combination device ormultipurpose utensil can be operated with one hand. It is completelysufi'lcient, after properly positioning the selector switch or lever 7,to carry out movements with the lever 2 in order to achieve aneffortless opening of the can.

(3) Operation of the device for carrying out further functions In orderto open bottles which are sealed with a metal cap the slide mechanism 41is displaced into the righthand terminal position of FIG. 3 until thescrew 46 impacts against the edge of the slot 47. Now, it is possible toremove the metallic closures from the bottles. In so doing, operation ofthe actuation lever 2 is not necessary, and therefore, it isadvantageously brought into its rest position where it bears snugly orflushly against the graspable housing 1 and retained in this position bymeans of the securing catch 3.

In the same position of the slide member 41 it is possible to use theworking edge 44, which has been sharpened for this purpose, to cut awaythe head portion of a cap arranged over the neck of the bottle forprotecting the cork. Then the upper portion of the cap can be removedand the cork is rendered accessible for pulling out of the bottle.

If the slide member 41 is placed into the left-hand terminal position,then the flexed or bent tip portion 45 can be pushed into the floor ofcans and other casks or containers to provide a pouring-or aerationopening.

A further possibility for cutting away a protective cap or hood for thebottle or the like is provided by the arrangement of a rotatably mountedcutting wheel 57 at the back of the operating lever 2. When thisoperating lever 2 assumes its effectual or operable position the cuttingWheel 57 is located at the region of the graspable housiig 1, shown inFIG. 3. The neck of the bottle is now placed and turned in the angulararea defined by the intersection of the back or rear portion of thegraspable housing 1 and the extended lever 2. Consequently, the cuttingwheel 57 cuts into the cap or hood enclosing the neck of the bottlewhich can then be removed. The cutting Wheel 57 is advantageously formedof material which can be hardened to be glass hard so that the cuttingWheel 57 also does not tend to become dull even during intensive use.This manner of cutting away bottle cap closures or protective hoods orseals has proven itself to be exceptionally simple and easy to perform.

As already explained, the multipurpose utensil or combination device ofthe invention is essentially formed of plastic components. Only theelements which are intensively used or subjected to stress, such as theneedle 6, the cutting wheels 9 aid 57, the rollers 10, the rollersupport 50, the springs 53, 18, and 39, the pinion 36, the transportWheel shaft 37 as well as a number of the bolts, are formed of partiallyhardened steel for instance.

The inventive multipurpose utensil or combination device of theinvention renders possible the performance of different types of Work inthe household and hotel and restaurant type commercial enterprises, byutilizing a single device which, however, is still capable of beingeasily manipulated without requiring the exertion of any large amount offorce and can be operated with one hand. Furthermore, the individualmultipurpose units possess particularly advantageous properties, forinstance, the special construction for the stroke of the cork pullermechanism in order to obtain for each piston stroke as large as possiblequantity of air, and through the features of th resilient roller membersfor the can opener mechanism by means of which the can can be pressedagainst the transport wheel.
